I once worked at a company that made learning management software for CEOs - basically those stupid HR click-thrus we all have to sit through. Problem was that CEOs at the time didn’t know how to use a scroll bar so if they encountered a screen with a scroll bar they either couldn’t continue or, after we moved the next button to the top of the screen, missed all of the content not on screen and couldn’t pass the tests. I could never figure out their issue. I encountered my first scroll bar on a Mac in a JC Penny way back when and had no issue with scrolling.
